SLIDING BEARING, BASE ISOLATION STRUCTURE, AND STOPPER FOR THE SLIDING BEARING
PROBLEM TO BE SOLVED: To cope even with unexpected great earthquake vibration while suppressing size increase and simplifying a structure.SOLUTION: A sliding bearing 20 includes a lower shoe 21 fixed on a lower structure, an upper shoe 22 fixed on an upper structure and arranged to be relatively displaced in a horizontal direction with respect to the lower shoe 21, and a slider 23 positioned between the lower shoe 21 and the upper shoe 22 and disposed on a sliding surface 24 provided on at least one of the lower shoe 21 and the upper shoe 22 to be slid in the horizontal direction. The slider 23 is slid on the sliding surface 24 to the horizontal direction in accordance with relative displacement of the lower shoe 21 and the upper shoe 22 to the horizontal direction, and to one of the lower shoe 21 and the upper shoe 22, a stopper 31 which regulates further relative displacement of the lower shoe 21 and the upper shoe 22 by being abutted to the other from the outer side of the horizontal direction when the lower shoe 21 and the upper shoe 22 are relatively displaced in the horizontal direction is connected.
【課題】大型化を抑制して構造の簡素化を図りつつ、想定外の大きな震動が生じたときにも対応する。【解決手段】すべり支承20は、下部構造に固定される下沓21と、上部構造に固定され、下沓21に対して水平方向に相対変位可能に配置される上沓22と、下沓21と上沓22との間に位置し、下沓21および上沓22のうちの少なくとも一方に設けられたすべり面24に、水平方向に滑動可能に配置されたスライダ23と、を備え、スライダ23は、下沓21と上沓22との水平方向への相対変位に伴って、すべり面24上を水平方向に滑動し、下沓21および上沓22のうちのいずれか一方には、これらの下沓21および上沓22が水平方向に相対変位したときに、いずれか他方に水平方向の外側から当接することで、下沓21と上沓22との更なる相対変位を規制するストッパ31が連結されている。【選択図】図5
